Humans share many basic body features with animals, since we are also animals. Although the features of animals may be similar, there is a wide range of variation, as all animals are specialized for their habitat.
Wild animals are particularly specialized, as their survival depends on it. Polar bears, for example, have much more hair on their bodies then we do because they live in a colder environment. Polar Bear hair is specialized for their particular environment, being white for camoflage, and hollow to trap in heat and aid flotation.
In this activity, students compare their own anatomical features to those of other animals.
